Patent number: 9441765Abstract: A piping component for controlling the flow of fluids that includes a piping body having an inlet end and an outlet end, including methods of operating such components within a piping system. The piping body may be sized for fluids operating at temperatures from approximately 350° F. up to approximately 500° F., and up to approximately 650° F. In addition, the piping body is made from a silicon-copper alloy consisting essentially of less than 16% zinc, less than trace amounts of lead, less than trace amounts of bismuth, 2 to 6% silicon and a balance of copper (by weight). In certain aspects, less than 0.09% of lead and/or less than 0.09% bismuth are contained in the silicon-copper alloy.Type: GrantFiled: November 16, 2015Date of Patent: September 13, 2016Assignee: NIBCO INC.Inventors: David A. Bobo, Mark A. Clark, Aaron W. Edds, Benjamin L. Lawrence, Charles M. Stutsman

Patent number: 9297477Abstract: A locking collar slideably fits over the control handle of a valve, such as a ball valve, and can be moved to locking and unlocking positions. The collar includes a pair of fork-like tines which are spaced apart to span a stop member on the valve body. One of the tines includes a tab with a threaded aperture for receiving a threaded adjustment screw. When tightened against the stop member, the screw secures the locking collar and, therefore, the valve handle in a fixed position, preventing inadvertent changing of the valve position. An aperture in the handle allows a lock to be inserted through the handle preventing movement of the locking collar to prevent changing of the valve position by unauthorized tampering.Type: GrantFiled: October 3, 2014Date of Patent: March 29, 2016Assignee: NIBCO Inc.Inventor: Keith W. Yoder

Patent number: 9261215Abstract: A plumbing fitting for coupling a water supply line to a second plumbing fitting includes a polymeric tailpiece having one end for coupling to a conduit and an opposite end with an outwardly extending annular flange having an annular face surface. A circular recess is formed in the face surface for receiving a seal. A nut is positioned over the tailpiece and has an inwardly extending annular rim engaging a side of the flange opposite the face surface. The nut is formed of a polymeric material having internal threads and integrally includes a metal insert extending in concentric spaced relationship to the threads of the nut. The insert includes an end which is threaded and forms a lead-in thread that is coaxial with the threads of the nut.Type: GrantFiled: April 18, 2013Date of Patent: February 16, 2016Assignee: NIBCO Inc.Inventor: Douglas A.

Patent number: 9188260Abstract: An O-ring has a flange which includes a plurality of slots, such that, when inserted into an annular groove of a pipe fitting before crimping, the slots allow the flow of fluid therethrough, such that an installation would not pass pressure tests until such time as a proper crimp has been made. Such a design allows the use of conventional push-on pipe connections by utilizing a unique O-ring seal which works in conjunction with standard push-on crimp-type pipe fittings and conventional crimping tools for subsequently sealing the connection. The O-ring is either circular or elliptical in cross section and the slots define equally spaced annular segments.Type: GrantFiled: July 30, 2009Date of Patent: November 17, 2015Assignee: NIBCO Inc.Inventor: Scott Lee Spence

Publication number: 20130192709Abstract: Copper alloys exhibiting enhanced oxidation resistance are provided by adding an amount of sulfur that is effective to enhance oxidative resistance. Such sulfur addition can be achieved by combining elemental forms of copper and sulfur and heating the mixture to form a molten alloy, or by forming a sulfur-rich pre-mix that is added to a base alloy composition. Forming a pre-mix provides improved homogeneity and distribution of the sulfur predominantly in the form of a metal sulfide.Type: ApplicationFiled: March 14, 2013Publication date: August 1, 2013Applicant: NIBCO INC.Inventor: NIBCO INC.

Patent number: 8113550Abstract: An adapter integrates a tail piece and connection for coupling to plumbing fittings utilizing a union nut or flange and provides a press-fit connection to the tail piece for installation in the system. The method of manufacturing the adapter comprises the steps of forming a flange on a section of conduit; placing a threaded union nut or mounting flange over the flange fitting; roll-forming an internal, concave annular recess into the section of conduit extending from the nut and inserting an O-ring into the recess for completing the adapter. The adapter can then be sealably attached to a plumbing fitting, such as a valve or the like, utilizing a conventional flat gasket between the flange of the adapter and the plumbing fitting. The installation is completed by inserting a conduit into the adapter to clear the O-ring and crimping the bead formed by the recess to complete the sealed connection.Type: GrantFiled: December 9, 2008Date of Patent: February 14, 2012Assignee: NIBCO Inc.Inventors: Steven J.

Patent number: 8052099Abstract: A versatile sway brace fitting, includes a pair of spaced jaws, for firmly and deformingly gripping a brace, and a method for manufacturing the fitting. The fitting can withstand substantial loads and is adaptable to receive a variety of braces such as bracing pipes, angle irons, channels, plates, among others. The fitting includes a set screw, preferably angled, and a sharp-cornered recess which assist in resisting withdrawal of the brace from the jaws. The method of manufacturing is desirably simple and expeditious, thereby ensuring that the fitting is inexpensive.Type: GrantFiled: February 24, 2010Date of Patent: November 8, 2011Assignee: Nibco Inc.Inventor: Richard W.
